Seared, sesame-crusted tuna with a crisp, tangy cucumber salad—bright, savory, and texturally crisp with nutty sesame notes.
Quick-Seared Sesame Tuna with a Bright Cucumber Crunch
A restaurant-style tuna steak that cooks in minutes, paired with a tangy, crunchy cucumber salad for a fast, elegant weeknight meal.
This is the kind of dinner that looks fancy but behaves like a weeknight meal: nutty sesame-crusted tuna seared until the outside is golden and the center is tender and pink, served alongside a crisp, vinegar-forward cucumber salad. The contrast — rich, almost buttery tuna against light, acidic cucumbers — keeps each bite interesting and refreshes the palate between richer mouthfuls of fish.
A few technique notes make all the difference. Pat the tuna dry, season simply with kosher salt and black pepper, then press into sesame seeds so they cling evenly; shake off any excess so the crust doesn’t burn. Heat a heavy skillet (cast iron is ideal) until very hot, add a splash of neutral oil, and sear the steaks 45–75 seconds per side for rare to medium-rare depending on thickness. Let the steaks rest 5 minutes before slicing thinly across the grain to reveal that perfect pink center.
The cucumber salad is quick to assemble: thinly sliced English cucumbers, scallions, and a dressing of low-sodium soy, rice vinegar, toasted sesame oil, grated ginger, and a little minced garlic. Toss and let it sit a few minutes so the flavors marry — the scallion whites and ginger go into the dressing for punch, and the green tops make a pretty, fresh garnish. If you like, make the dressing ahead; the cucumbers will stay delightfully crisp if you drain any excess liquid.
Serve the tuna slices over a bed of greens, steamed rice, or simply beside the salad, drizzling extra dressing and a scattering of sesame seeds and scallion greens. It’s quick enough for a Monday night but polished enough for company, and while the tuna is best the day it’s seared, the cucumber salad holds well for a day in the fridge, making this a flexible, flavorful option for many meals.
Ingredients
How to Make Tuna Steak Sesame Cucumber Salad
- Pat tuna steaks dry with paper towels and season both sides with the kosher salt and black pepper.
- Spread the sesame seeds on a plate and press each tuna steak into the seeds to coat both sides lightly, shaking off any excess.
- Heat a heavy skillet or cast-iron pan over medium-high until very hot, add the neutral oil, then sear tuna 45–75 seconds per side for rare–medium-rare (adjust time for thickness); transfer to a cutting board and let rest 5 minutes.
- While the tuna rests, thinly slice the cucumbers (half-moons or matchsticks) and thinly slice the scallions (white and green parts separated if you like).
- Whisk together the low-sodium soy sauce, rice vinegar, toasted sesame oil, grated fresh ginger, minced garlic, honey, and the juice of the lime; taste and adjust with a pinch of salt or more lime if needed.
- Toss the sliced cucumbers and scallions with most of the dressing (reserve 1–2 tbsp for serving) and let sit 3–5 minutes so the flavors meld.
- Slice the rested tuna thinly against the grain and arrange over or alongside the dressed cucumber salad; drizzle the reserved dressing over the tuna.
- Finish with an extra sprinkle of sesame seeds and additional sliced scallion greens, and serve immediately with lime wedges on the side.
